 *
 *     "Object" form shall mean any form resulting from mechanical
 *     transformation or translation of a Source form, including but
 *     not limited to compiled object code, generated documentation,
 *     and conversions to other media types.
 *
 *     "Work" shall mean the work of authorship, whether in Source or
 *     Object form, made available under the License, as indicated by a
 *     copyright notice that is included in or attached to the work
 *     (an example is provided in the Appendix below).
 *
 *     "Derivative Works" shall mean any work, whether in Source or Object
 *     form, that is based on (or derived from) the Work and for which the
 *     editorial revisions, annotations, elaborations, or other modifications
 *     represent, as a whole, an original work of authorship. For the purposes
 *     of this License, Derivative Works shall not include works that remain
 *     separable from, or merely link (or bind by name) to the interfaces of,
 *     the Work and Derivative Works thereof.
 *
 *     "Contribution" shall mean any work of authorship, including
 *     the original version of the Work and any modifications or additions
 *     to that Work or Derivative Works thereof, that is intentionally
 *     submitted to Licensor for inclusion in the Work by the copyright owner
 *     or by an individual or Legal Entity authorized to submit on behalf of
 *     the copyright owner. For the purposes of this definition, "submitted"
 *     means any form of electronic, verbal, or written communication sent
 *     to the Licensor or its representatives, including but not limited to
 *     communication on electronic mailing lists, source code control systems,

 *     Licensor for the purpose of discussing and improving the Work, but
 *     excluding communication that is conspicuously marked or otherwise
 *     designated in writing by the copyright owner as "Not a Contribution."
 *
 *     "Contributor" shall mean Licensor and any individual or Legal Entity
 *     on behalf of whom a Contribution has been received by Licensor and
 *     subsequently incorporated within the Work.
 *
 *  2. Grant of Copyright License. Subject to the terms and conditions of
 *     this License, each Contributor hereby grants to You a perpetual,
 *     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 *     copyright license to reproduce, prepare Derivative Works of,
 *     publicly display, publicly perform, sublicense, and distribute the
 *     Work and such Derivative Works in Source or Object form.
 *
 *  3. Grant of Patent License. Subject to the terms and conditions of
 *     this License, each Contributor hereby grants to You a perpetual,
 *     worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 *     (except as stated in this section) patent license to make, have made,
 *     use, offer to sell, sell, import, and otherwise transfer the Work,
 *     where such license applies only to those patent claims licensable
 *     by such Contributor that are necessarily infringed by their
 *     Contribution(s) alone or by combination of their Contribution(s)
 *     with the Work to which such Contribution(s) was submitted. If You
 *     institute patent litigation against any entity (including a
 *     cross-claim or counterclaim in a lawsuit) alleging that the Work
 *     or a Contribution incorporated within the Work constitutes direct
 *     or contributory patent infringement, then any patent licenses
 *     granted to You under this License for that Work shall terminate
 *     as of the date such litigation is filed.
 *
 *  4. Redistribution. You may reproduce and distribute copies of the
 *     Work or Derivative Works thereof in any medium, with or without
 *     modifications, and in Source or Object form, provided that You
 *     meet the following conditions:
 *
 *     (a) You must give any other recipients of the Work or
 *         Derivative Works a copy of this License; and
 *
 *     (b) You must cause any modified files to carry prominent notices
 *         stating that You changed the files; and
 *
 *     (c) You must retain, in the Source form of any Derivative Works
 *         that You distribute, all copyright, patent, trademark, and
 *         attribution notices from the Source form of the Work,
 *         excluding those notices that do not pertain to any part of
 *         the Derivative Works; and
 *
 *     (d) If the Work includes a "NOTICE" text file as part of its
 *         distribution, then any Derivative Works that You distribute must
 *         include a readable copy of the attribution notices contained
 *         within such NOTICE file, excluding those notices that do not
 *         pertain to any part of the Derivative Works, in at least one
 *         of the following places: within a NOTICE text file distributed
 *         as part of the Derivative Works; within the Source form or
 *         documentation, if provided along with the Derivative Works; or,
 *         within a display generated by the Derivative Works, if and
 *         wherever such third-party notices normally appear. The contents
 *         of the NOTICE file are for informational purposes only and
 *         do not modify the License. You may add Your own attribution
 *         notices within Derivative Works that You distribute, alongside
 *         or as an addendum to the NOTICE text from the Work, provided
 *         that such additional attribution notices cannot be construed
 *         as modifying the License.
 *
 *     You may add Your own copyright statement to Your modifications and
 *     may provide additional or different license terms and conditions
 *     for use, reproduction, or distribution of Your modifications, or
 *     for any such Derivative Works as a whole, provided Your use,
 *     reproduction, and distribution of the Work otherwise complies with
 *     the conditions stated in this License.
 *
 *  5. Submission of Contributions. Unless You explicitly state otherwise,
 *     any Contribution intentionally submitted for inclusion in the Work
 *     by You to the Licensor shall be under the terms and conditions of
 *     this License, without any additional terms or conditions.
 *     Notwithstanding the above, nothing herein shall supersede or modify
 *     the terms of any separate license agreement you may have executed
 *     with Licensor regarding such Contributions.
 *
 *  6. Trademarks. This License does not grant permission to use the trade
 *     names, trademarks, service marks, or product names of the Licensor,
 *     except as required for reasonable and customary use in describing the
 *     origin of the Work and reproducing the content of the NOTICE file.
 *
 *  7. Disclaimer of Warranty. Unless required by applicable law or
 *     agreed to in writing, Licensor provides the Work (and each
 *     Contributor provides its Contributions) on an "AS IS" BASIS,
 *     WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
 *     implied, including, without limitation, any warranties or conditions
 *     of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
 *     PARTICULAR PURPOSE. You are solely responsible for determining the
 *     appropriateness of using or redistributing the Work and assume any
 *     risks associated with Your exercise of permissions under this License.
 *
 *  8. Limitation of Liability. In no event and under no legal theory,
 *     whether in tort (including negligence), contract, or otherwise,
 *     unless required by applicable law (such as deliberate and grossly
 *     negligent acts) or agreed to in writing, shall any Contributor be
 *     liable to You for damages, including any direct, indirect, special,
 *     incidental, or consequential damages of any character arising as a
 *     result of this License or out of the use or inability to use the
 *     Work (including but not limited to damages for loss of goodwill,
 *     work stoppage, computer failure or malfunction, or any and all
 *     other commercial damages or losses), even if such Contributor
 *     has been advised of the possibility of such damages.
 *
 *  9. Accepting Warranty or Additional Liability. While redistributing
 *     the Work or Derivative Works thereof, You may choose to offer,
 *     and charge a fee for, acceptance of support, warranty, indemnity,
 *     or other liability obligations and/or rights consistent with this
 *     License. However, in accepting such obligations, You may act only
 *     on Your own behalf and on Your sole responsibility, not on behalf
 *     of any other Contributor, and only if You agree to indemnify,
 *     defend, and hold each Contributor harmless for any liability
 *     incurred by, or claims asserted against, such Contributor by reason
 *     of your accepting any such warranty or additional liability.
 *
 *  END OF TERMS AND CONDITIONS
 *
 *  APPENDIX: How to apply the Apache License to your work.
